this is only Beta at the moment. No time for documentation, sorry. But it would be great is any other person would like to take part of it.
To your problem. Be sure that both number toolbar buttons 1 + 2 are switched on.
Another possibility is to rename the wdeConfig.xml file.
C:\Users\<your user account name>\AppData\Local\jdSoftwareSolutions\WDE\0.3.7.0
I hope this will be helpfull for you
